LEWIS fr. WILOOX. or PEEKSK'ILL, new YORK.

To all lwhom t may concern:

iBe it known that I, 'LEWIS T. WILCOX, a citizen of the United States, and a resident of Peekskill, in the county of Westchester,

State of New York, have .invented certain new and useful Improvements in Gas-Burners, of whrch the following isa specification. f

The/invention relates to burners adapted to use gaseous fuel, and its objects are, among others, to provide simple and effec-rtive means for controlling the flow of the fuel to a burner for lighting the burners simultaneously or successively from a common p1lot light, and for producing and controlling a low simmering fiame, and for protecting the parts against impairment by the accumulation of carbon; and to provide means for guarding against various un;

desirable results which vsometimes follow The improvements consist in th'construction, combination and arrangement of parts hereinafter described and claimed, and illustrated in the accompanyin drawings.

In the said drawings, Figure 1 is aside elevation of a burner and its connections, partly in vertical-medial cross-sectiomjembodying the improvements, Fig. 2 is a plan of the same' with the `valve and burner in horizontal cross-section. Fig. 3 is a plan of the said parts with a broken off portion of a second burner adjacent thereto, the distance between 'the burners being shortened for convenience in drawing. Figs. 4, 5 and 6 are views similar to Figs. l, 2 and 3 of a modified form. Fig. 7 is a view of parts of the burner shown in Fig. 4 taken on the cross-section line 7-7 of Fig. 4:, andlooking in the direction indicated by the arrows. Figs 8, 9, and 10 are views similartoFigs. 1,V 2 and 3 of another modification, Fig. 11 is a view of some of the parts shown in`Fig. 8,

Y modified construction' in which the burner and ad]acent parts are screw-threaded to the hood below them;

Referring to the preferred form illustrated ,in Figs. 1 to 3 inclusive, fuel is supplied to the urner through the branch passageway 1 communicating -witha gas supply Apipe 2 shown in dotted lines. This branch passageway has a by-pass 3 provided with ranch ways 4 and 5 which communicate through the ways of the valve plug -with the tubes 7 and 8, respectively, and tube 7 supplying gas to the burner 10 and the tube 8 to the p'ilot light 11. The branch 1 also communicates directly through va way inthe valve plug with the pipe 9 which supplies fuel to the flash lightingiburner 12. rI`he ways controlled by the valve plug'are preferably formed in the valve body 13, which consists of a single'casting provided with a central vertical aperture for` the valve plug, and also a small aperture in which-is threaded the needle valve V14: for independently regulating and shutting olf the supplyy o f gas to the pilot light?. The valve plug is rovided with a suitable handle 15 by which 1t may be turned, and is held in the valve body bya screw bolt 16 and washer 17.

The ways of the valve 18, 19, and Q0 communicate with the supply pipes 8, 7 and 9 respectively, the way 18 consisting of a` groove extending more thanlialf way around the plug, and the ways 19 and 20 consisting of bores through the plug having their outer ends out f vertical line but overlapping slightly, and theirinner ends also out of line. In this ina-nner means are provided for supplying fuel to the pilot light constantly while the supply to the burner and Hash lighter is manipulated, and also means for supplying fuel to the two latter simultane- When the valve 1s turned to the position shown in Fig. 2 the lighter is supplied with fuel and caused to .the burner 10 and the lighter are suppliedwith fuel simultaneously, and if the 'Valve ratentea rien-eo, rein'. f Application led August 18, 1914.

be ignited from the pilot light and to flash beturned farther the lighter is cut off while the burner 10 remains in communication with its fuel supply, and if the valve be turned still farther both are cut off. During these movements of the valve the supply to the pilot light through the channel 18 is 'i maintained. "If now it is desired to cut this off alsothe valve may be turnedstill farther in the same direction until the end of the said channelepasses its supply conduit 5, Whenall three tubes leading to the burner will be closed.' This may also be done by turning thevalve back-in counter clockwise direction-beyond 'its originalposition until the opposite end of the groove or channel 18 passes the'way 5. v It will be understood that the valve may be provided with a suitable indicator to show theoperator when it is in the various positions just described,

and that in -connection With this indicator a spring or other' check may be provided toy indicate to the operator when the valve is in passage way 21, inthe casting 22, and the .posite the orifices 31.

jet nozzle 23 with the'flue 24, air being admitted for admixture with the gasvat the lower edge of the burner hood and shield 25, and the mixture burning as it issues from the vents 26 ofthe top plate or cover of the burner proper 1.0. A downward Vent- 27 extends from the interior chamber of the burner 10 to approximately the level of Y one of the openings 31 in the upper part of the hood 25 and in yproximity to the upper edge of said opening, so that the burnermay be ignited from the flash lighter although isolated by its bottom partition from the space within the hood 25.

The tube J9 supplying fuel to the flash light communicates with the passage 29 in the casting 22 and through it with the tube 28, which is closed at its upper cnd by the burner 12 except forthe side vents 30 op- The fuel, therefore, passes out through these vents, is ignited and passes laterally through the openings 31 in the process of combustion.

A jet nozzle 32 passes a small portion of the gas into the. mixing chamber 33, which is. supplied with air entering beneath the lower edge of the hood 25. From this chamber it issues through the screen 34 to the interior of the hood where it will be ignited by the pilotlight 11 and in turn cause the flash burner 12to light. The fillin of the space around the burner 12 with tie mixturc prevents the formation of carbonv on the parts which would take place if the gas were ignited without the intervention of this mixture, and the screen 34 will prevent back fire.

An important function is also erformed l by the arrangement which provi es for the mixture adjacent to the point of combustion, as the friction of the tube, When the mixture '1s made near the valve or at another point distantfrom the burner, tends to overcome 'pilot light, which involves the use of a tube of relatively small diameter. The presence i of the mixture in the hood and surrounding the lighter. also insures the lighting of all the vents of the flash burner and the consequent lighting of the other burners of the stove.

The pilot light tube 8 terminates in the upper part of the hood 25 and serves the purpose of igniting the flash burner 12 whenever desired, and through it the burners 10 and the adjacent burners of the stove, such as 35.

It will be seen from the foregoing description that in order to light the burner 10 while the pilot light is burning it is only necessary to turn lthe valve to open communication between the burner and the gas supply, through the way 1S), and this movement simultaneously supplies the flash burner with fuel to ignite it. lf it is desired to use the adjacent burners and extinguish the burner 10 the movement of the valve handle is continued in the same direction until first the flash burner and then the burner 1() has been cut off, or it may be turned in the opposite direction. If it is desired merely to ignite the adjacent burners without igniting the burner l() the valve is turned far enough only to ignite the flash and then turned back to its original position, which is the position shown in Fig. l, or it may be turned on quickly past the point at which communication is established With Jthe said' burner.

The number of burners to be lighted from the flash burner will determine the number of orifices 31. The construction shown is adapted to be used with a four burner stove and therefore has four of said orifices. These burners may be controlled in the ordi- 'nary way by means of a valve on the gas supply pipe, and one or more may be ignited and used in connection with the lighting apparatus as desired.

The burner l0, as shown, is constructed to be used as a low flameor simmering burner, but it may be replaced by a burner of the same construction as the others; 1n order that it may be converted into a burner of different character the upper portion may be screw threaded to the hood 25 (see Fig. 13) and the burner cap which is to replace it provided with corresponding threads, or the conversion may be provided for in other manner.

' In the modification of Figs. 4 to 7 inclusive, the burners are arranged in slibstantially the same manner` as in the preferred form, but the tubes 37 and 38 through which fuel is supplied to the burner 10 and pilot light respectively communicate with relata@ the gas supply through a4 common .groove or channel 39, vin the valve plug, their ports being in one horizontal plane and below the flash light tube and the groove being so uarra'nged that when the valve is in its closed position with respect to'the other tube the tube 38 is in communication with the supply.`

When the valve'plug is turned toward its open position it opens the tube 9 and then y 10 brings the end ofthe groove 39' opposite the port of tube 37.- This provides for the performance of the same functions as that described with reference to the preferred form. j

ln the modification of Figs. 8 to 11 inclusive the burner isof substantially the same construction as that shown in the other figures, except that the tube 24 is at the side of the tube 28 and `the pilot light located at on'e side of and partly between the two.

In this modification the tubes` 9 and 37 which supply gas to the lighter and the burner 10 i respectively'are in horizontal plane, and the tube 38 supplyingl the pilot light below them. This provides for the use'oi a groove t() for the pilot 'light alone and a single way 3G for the other two.' 'llhe ends of this way are flared so thati't may be in communica-` tion with both conduits 9 and 37 at the f same time, but may be moved so as to open the former without openingthe latter and close the former w'i-thoutjclosing-the latter after both have been`opened.
